USB 2.0 High-Speed (480 Mbps) Signal Switch

Description

The PI3USB102 is a single differential channel 2:1 multiplexer/de-

multiplexer USB 2.0 Switch. Industry leading advantages include a

propagation delay of less than 250ps, resulting from its low channel

resistance and I/O capacitance. The device multiplexes differential

outputs from a USB Host device to one of two corresponding outputs.

The switch is bidirectional and offers little or no attenuation of the

high-speed signals at the outputs. It is designed for low bit-to-bit

skew, high channel-to-channel noise isolation and is compatible

with various standards, such as High Speed USB 2.0 (480 Mb/s).

The PI3USB102 offers over voltage protection per the USB 2.0

speciﬁ cation. With the chip powered on or off, all I/O pins can

withstand a short to Vbus (5V +/-10%). This feature can only be

offered if a 100-ohm pull up resistor is placed between V

to the power supply.

In situations where Vbus can be as high as 7V, Pericom recommends

changing the resistor value from 100ohm to 200ohm. Pericom can

still support over-voltage protection up to 7V, as long as the 200ohm

resistor is present.
